Date: Mon, 16 Jul 2007 16:28:14 +0200 (CEST) From: "M. Koehrer" <mathias_koehrer@...or.de> To: linux-kernel@...r.kernel.org Subject: CONFIG_PREEMPT_RT Patch and UDP/IP on Ethernet in real time. Hi everybody, I have a question concerning Ingo Molnar's realtime preempt patch. This patch is great go get low latency on timer threads and a really good real time behaviour. I want to connect an external, embedded device via Ethernet (UDP/IP) to my Linux PC. This communication should be in real time as well. For this I have a separate network adapter in my PC that is used solely for this UDP Ethernet traffic. However, I think all Ethernet traffic is be handled by the soft IRQ threads [softirq-net-rx] [softirq-net-tx] but I do not see a way to do real time networking via my dedicated network adapter. How can I get this UDP networking real time capable? I use kernel 2.6.21.6 and the related realtime preempt patch. However, this is a general question that is not related to a certain kernel version. Any feedback is welcome. Thanks a lot! Regards Mathias -- Mathias Koehrer mathias_koehrer@...or.de Viel oder wenig? Schnell oder langsam?
